Cisco MDS 9000 Series Configuration Guide

Clearing the Time Stamp
You can clear time stamps only from the Cisco MDS switch—not the mainframe.
Note
Use the clear ficon vsan vsan-id timestamp command in EXEC mode to clear the VSAN clock.
switch# clear ficon vsan 20 timestamp
Configuring SNMP Control of FICON Parameters
To configure SNMP control of FICON parameters, follow these steps:
Step 1 switch# config t
switch(config)#
Enters configuration mode.
Step 2 switch(config)# ficon vsan 2
switch(config-ficon)#
Enables FICON on VSAN 2.
Step 3 switch(config-ficon)# no snmp port control
Prohibits SNMP users from configuring FICON parameters.
Step 4 switch(config-ficon)# snmp port control
Allows SNMP users to configure FICON parameters (default).
About FICON Device Allegiance
FICON requires serialization of access among multiple mainframes, CLI, and SNMP sessions be maintained
on Cisco MDS 9000 Family switches by controlling device allegiance for the currently executing session.
Any other session is denied permission to perform configuration changes unless the required allegiance is
available.
This task discards the currently executing session.
Caution
Clearing FICON Device Allegiance
You can clear the current device allegiance by issuing the clear ficon vsan vsan-id allegiance command in
EXEC mode.
